<p>CompositeImage() returns the second image composited onto the first at the specified offset, using the specified composite method.</p>

<p>The format of the CompositeImage method is:</p>

<pre class="text">

  const Image *source_image,const CompositeOperator compose,
  const MagickBooleanType clip_to_self,const ssize_t x_offset,
  const ssize_t y_offset,ExceptionInfo *exception)

<dt>compose</dt>
<dd>This operator affects how the composite is applied to the image.  The operators and how they are utilized are listed here http://www.w3.org/TR/SVG12/#compositing. </dd>

<dd> </dd>
<dt>clip_to_self</dt>
<dd>set to MagickTrue to limit composition to area composed. </dd>
